The developed high-entropy bulk metallic glasses (HE-BMGs) provide a new strategy to design and synthesis BMGs. More importantly, the HE-BMGs possess excellent mechanical and physical properties inherited from the advantages of both HEAs and BMGs, and show great potential for practical applications. In this work, we reported new FeCoNi(P, C, B) HE-BMGs with large supercooled liquid region (Δ<I>T</I><SUB>x</SUB>), and excellent soft magnetic and mechanical properties. Fully HE-BMG rods were successfully prepared by copper mold casting method. The developed HE-BMGs possess low glass transition temperature (<I>T</I><SUB>g</SUB>) and large Δ<I>T</I><SUB>x</SUB>. The alloys also exhibit good soft magnetic and mechanical properties. The mechanism of good thermal stability of the supercooled liquid for the present HE-BMGs was discussed in terms of the precipitated phases during crystallization. The developed HE-BMGs with good thermal stability, and soft magnetic and mechanical properties give excellent promise for making MEMS/NEMS devices by thermoplastic processing.
